Speaking today at the Flight 93 memorial in Pennsylvania today, Vice President Joe Biden called 9-11 a "bittersweet moment."

"And its an honor, a genuine honor to be back here today but like all of the families, we wish we weren't here. We wish we didn't have to be here. We wish we didn't have to commemorate any of this." Biden said. "It is a bittersweet moment for the entire nation, for all of the country, particularly for those family members gathered here today."

There has been some questions raised on Twitter about the meaning of Biden's comments but people should probably give Biden some space. If you are commemorating Flight 93; that specific event is one of both heroism and tragedy.

Prior to these remarks, Biden specifically mentions that the families of 9-11 are seeing one another again, and how that experience can be healing.

"In my experience, I imagine that you all find solace in seeing one another, there's nothing like being able to talk with someone who you know understands," he said.
